I understand the time pressure, especially when a stretch is billed as 'not worth the walk' ...and I've read often in this forum about people skipping this section. I wondered the same thing about the step on the Norte between Bilbao and Portugalate...I walked it but wouldn't again. For me that is because it was often just walking in industrial areas, and even the pretty first part was a walk in a park...little of what drew me to the Camino. Others liked the park and didn't mind the industrial. When I do my next camino, I am adding on this stretch between Burgos and Leon because I wanted to do it the last time but ran out of time. That's because it has many churches, monasteries, and museums I want to see, and what sounds like an amazing albergue. You might consider what appeals the most to you: landscape, history, art, etc and look at a guide/photos to determine what this stretch offers to you in terms of what you want. You could also start out on it, and if it's not what you want, taxi back to Burgos then move on to Leon.
